Chauvin Arnoux D34N [P01120053A] 500A/1000A/1500A AC Current Probe Adapter. The Chauvin Arnoux D34N 500A/1000A/1500A (5A AC)[F] Current Probe lets you take accurate and exact measurements of heavy currents that reach up to 3000A AC. The current clamp can take readings without making direct contact, and the large rectangular clamp opens to a maximum of 90mm. This provides the ability to test cables and conductors that other current clamps simply can’t.  The Chauvin Arnoux D34N AC 500A/1000A/1500A (5A AC)[F] Current Probe also offers True RMS capabilities that allows for exact signal reproduction. This model is designed to be used for oscilloscopes and other devices that use a BNC interface. It can take measurements of low phase displacement, high bandwidth and exact change.  The robust frame of the device makes it perfect for working on the field, and can quickly connect up with most of your measuring equipment.
